Error 13.33.00 hp 4345 - HP LaserJet 4345mfp Printer

99% of 49 errors are caused by outdated firmware, which is the operating system of the printer. Go to http://h20564.www2.hp.com/hpsc/swd/public/readIndex?sp4ts.oid=415205&lang=en&cc=ca and download the current firmware. Select Windows 7 32bit as the firmware files there will install from any operating system. Also ensure that you have a 4345 and not an M4345, as they are different machines and use different firmware. Follow the instructions to install on your printer. I recommend the Easy Firmware Updates as it works all the time whereas using the RFU method can often result in a time out error, if your existing firmware is too old. Be patient, if your existing firmware is too old, it can take a long time to install. The only other catch is if you have a print job stuck in your printer queue on your PC you will need to clear that first so you can install the firmware as the printer must be at a ready state for the upgrade to work.

HP Laser jet 4345 mfp has 58 04 error HP Enterprise Business Community

Check inside the MFP (manual feed tray) for a scrap or a whole sheet of paper.
There is one of three sensors that is sending a paper jam notice to the printer.

Hi!

According to HP service manuals, the error you described is in the category:

JAM INSIDE TOP COVER AREA

and more specific:

The pre-feed sensor, the top-of-page sensor, or the fuser-delivery

Those are the points where some paper pieces or even dust can be stuck.


Hope it helped,

Bogdan

If safety is not caught up paper, paper pick rollers probably replace worn or cleaned rollers

check output bin sensor

This is a firmware error. Switch off and on the printer. Upgrade the firmware. Try printing from different documents and applications.
